6in1 Aquarium Filter Pump Fish Tank Submersible Silent Air Oxygen Aerator Internal Water Pump Aquarium Air Pump Wave Maker 220v

Instructions for Use

1. The product must be fully submerged in water before turning on the power.

2. Check whether the voltage in your country meets the product’s operating standards.

Product voltage: 220 V–240 V

3. Installation and Securing: Remove the included suction cups, snap them into the three grooves on the back of the product, and securely attach the entire unit to the side of the fish tank to prevent it from floating or swaying in the water.

4. Operating Requirements: The pump head must remain fully submerged below the water surface at all times.

5. Troubleshooting for No Bubbles: Connect the included air tube and check valve to the port (located above or to the left of the outlet). To use the check valve: turn clockwise to reduce airflow; turn counterclockwise to increase airflow.

6. Aquarium Size Compatibility: If the product does not match the aquarium’s specifications, you may remove the internal filter layer (it is recommended to keep the fish toilet component). After adjustment, the entire unit must still be fully submerged in water to operate.

Regular Cleaning

1. It is recommended to perform a complete cleaning every 1–7 days (1 week) to prevent the buildup of dirt and impurities that could cause blockages, ensuring smooth water flow and optimal performance. (⚠️ If the air output decreases, be sure to clean it promptly; prolonged blockages can lead to increased pressure within the device and shorten its service life.)

2. ⚠️ Be sure to disconnect the power before cleaning; never clean while the unit is powered on (never run the unit dry without water).

3. After cleaning, fully submerge the entire unit in water and confirm that it is completely submerged before reconnecting the power and starting the unit.

4. Be sure to clean the half-layer sponge promptly to prevent clogging; do not use high-density filter media, as such materials have poor water permeability and are prone to accumulating dirt and clogging. Routinely inspect all filter media; clean soiled parts in batches and replace aged consumables promptly to ensure smooth water circulation.

Troubleshooting

Low airflow: Check whether the water hose and check valve are installed; the check valve can be adjusted to regulate airflow.

Excessive noise during operation: This is typically caused by the unit not being fully submerged in water. If you hear unusual noises, immediately disconnect the power supply, reinstall and secure the unit, and ensure the water level fully submerges the entire unit. Only reconnect the power after proper adjustment.

Note

Regular cleaning is essential. If the sponge becomes clogged, water cannot effectively enter the machine, which will directly cause the unit to dry out and burn out.
